How can we create complex line types with including text ? For eg:- - - - - cctv - - - -

There is a file name acad.lin exist in your AutoCAD installation folder then inside enu then inside support folder. double click on this file then it will open to you a word pad and you will see all the types of lines there. Search for complex lines section then take copy from any line then paste it then modify it as the shape you need then make save and exit. Go to your AutoCAD then choose the line type and make load and click on file button then choose that updated file location then load and you will see your new lines there.

I hope Mr.Ahmed Shawky  gave you answer..
